To know oneself, one should assert oneself.

The dog that trots about finds a bone.

After a storm comes a calm.

If you think you can do it, you can.

By failing to prepare, you are preparing to fail.

Know or listen to those who know.

Without hard work, nothing grows but weeds.

If you've got a talent, protect it.

To be a good loser is to learn how to win.
